Title: Improvements relating to electricity measuring apparatus
IPC: G08C19/00
Filed: 1933-02-06
Abstract: 412,331. Counting-apparatus; electric supplymeters; electromagnetic switches. CHAMBERLAIN & HOOKHAM, Ltd., and JAMES, S., 4, New Bartholomew Street, Birmingham. Feb. 6, 1933, No. 3545. [Class 106 (i).] Apparatus for registering electrical impulses comprises a contact device whereby the impulses can be sent through a counter or diverted through an alternative path, and a cancelling coil for operating the contact device, the apparatus being used with two groups of circuits in such a manner that each impulse sent through the cancelling coil from one group prevents actuation of the counter by a succeeding impulse from the other group, the difference between the numbers of impulses from each group being thus obtained. In the embodiment described there are five electricity meters and when a predetermined amount of energy has passed through a meter corresponding contacts a, b are closed. The group of three upper meters registers the output from three generators and the group of two lower ones registers energy used for certain purposes, it being desired to obtain the difference between these two amounts on a counter o. A rotating arm f energizes in turn each circuit a, b. If a pair of the upper-group contacts a, b have been closed an impulse is passed through counters d, q, and contacts h, i to the counter o. If lowergroup contacts a, b are closed an impulse proceeds through counters d, r, contacts l, m, and a cancelling coil p, avoiding the counter o. The cancelling coil opens the contacts h, i, closes contacts h, j and opens contacts l, m. Hence, the next succeeding upper-group impulse does not affect the counter o, so that the lower-group impulse has been in effect subtracted from o. The said upper-group impulse passing through the cancelling coil p closes the contacts h, i, l, m. If, during the rotation of the arm f, an upper-group impulse does not succeed a lower-group one, the fact that the contacts l, m are open prevents a second lower-group impulse being " lost " through the coil p. Each pair of contacts a, b is reset by a coil c. Electromagnetic switches. The operating arrangements for the contacts h .. l are shown in Fig. 2. When an impulse passes through the cancelling coil p an arm v is raised and lowered and a pawl y carried by the arm actuates a ratchet wheel 4 connected to a cam wheel 5. A tooth of the cam wheel acts on the roller 8 of an arm 9 attached to a spring strip g whereby the contacts h, i and l, m, are opened and the contacts h, j closed. The next impulse passing through the coil p rotates the cam wheel another step whereby the roller 8 falls into a hollow and the contacts revert to the connections shown in Fig. 1. Specifications 315,204 and 333,170, [both in Class 106 (i)], are referred to.
